Ubuntu 6.06 LTS / 6.10 / 7.04 : tar vulnerability (USN-506-1)

Ubuntu Security Notice (C) 2007-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Dmitry V. Levin discovered that tar did not correctly detect the '..'
file path element when unpacking archives. If a user or an automated
system were tricked into unpacking a specially crafted tar file,
arbitrary files could be overwritten with user privileges.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected tar package.

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.9
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
